The Integrative Late Childhood Temperament Inventory: A New Multi-Informant Measure to Assess Six Basic Dimensions of Temperament In School-Aged Children

This study developed the Integrative Late Childhood Temperament Inventory (ILCTI) to assess six temperament traits in children aged 8–14. Across two studies, parent, self-, and teacher ratings showed good psychometric properties. Interrater agreement was moderate, and larger parent–teacher discrepancies were associated with children’s emotional and behavioral problems.
